Abstract
The karyotype of a mouse trapped in a hybrid zone between a Robertsoni an (Rb) population (2n = 22) and a population with the standard karyot ype (2n = 40-all-telocentrics) shows two Rb chromosomes with new arm c ompositions. We suggest that whole-arm reciprocal translocations betwe en Rb chromosomes gave rise to the new chromosome constitution and tha t such events can greatly help in understanding house mouse karyotype diversification and chromosomal speciation.
